Commissariat Store is located in Brisbane, Queensland bordered by William Street, Queen's Wharf Road and the Brisbane River, the birthplace of Queensland. The heritage listed building is one of only two surviving buildings from the convict period in Queensland, and is one of only four surviving commissariat buildings in Australia. It is the second oldest building in Queensland, dated to 1829, the oldest building being the Windmill at Wickham Park, dated to 1828. However, the Commissariat Store is the oldest occupied building in Queensland, as it is currently occupied by Royal Historical Society of Queensland . The Commissariat Store was originally built by convict labour under the direction of Captain Logan as a permanent Commissariat Store for the Moreton Bay Penal Settlement. Presently, the restored and renovated building operates as the headquarters for the RHSQ, housing the museum, Welsby Library, and functions.
